Chromosome segment substitution lines; Kernel row number; Maize (Zea mays L.); Quantitative trait loci

Unveiling the genetic architecture of grain yield and yield-related traits is useful for guiding the genetic improvement of crop plants. Kernel row number (KRN) per ear is an important yield component, which directly affects the grain yield of maize. In this study, we constructed a set of 130 chromosome segment substitution lines (CSSLs), using Nongxi531 as the donor parent and H21 as ... more

Classical swine fever; Immunoglobulin G; Lysozyme; Quantitative trait loci; Swine

Increased disease resistance through improved general immune capacity would be beneficial for the welfare and productivity of farm animals. Classical swine fever (CSF) is a contagious disease in farm animals. The immunoglobulin G (IgG) blocking percentage of CSF virus (CSFV) in serum is an essential diagnostic parameter in veterinary practice. In addition, lysozymes are a part of the ... more

Doubled haploid population; Flag leaf; Quantitative trait loci; Rice

Two rice doubled haploid (DH) populations derived from the crosses of ZYQ8/JX17 and CJ06/TN1 were used to detect quantitative trait loci (QTLs) for flag leaf length (FLL), width (FLW), and angle (FLA) under long-day conditions in Hangzhou (subtropical zone) and short-day conditions in Hainan (tropical zone), China. The four parents differed significantly in all 3 traits. FLL was found to ... more

Chili Pepper; Complex trait; Genetic map; Molecular markers; Quantitative trait loci

Genetic mapping is very useful for dissecting complex agronomic traits. Genetic mapping allows for identification of quantitative trait loci (QTL), provide knowledge on a gene position and its adjacent region, and enable prediction of evolutionary mechanisms, in addition to contributing to synteny studies. The aim of this study was to predict genetic values associated with different ... more

Quantitative trait loci; Rice; Seed-shattering genes; Sequence characterized amplified region marker; Simple sequence repeat

Seed shattering of wild plant species is thought to be an adaptive trait to facilitate seed dispersal. For rice breeding, seed shatter­ing is an important trait for improving breeding strategies, particularly when developing lines use interspecific hybrids and introgression of genes from wild species. We developed F3:4 recombinant inbred lines from an interspecific cross ... more

Bayesian shrinkage analysis; common bean; Plant breeding; Quantitative trait loci; Sclerotinia sclerotiorum

In this study, we identified simple sequence repeat, ampli­fied fragment length polymorphism, and sequence-related amplified poly­morphism markers linked to quantitative trait loci (QTLs) for resistance to white mold disease in common bean progenies derived from a cross between lines CNFC 9506 and RP-2, evaluated using the oxalic acid test and using Bayesian analysis. DNA was extracted ... more

Grain shape; Grain weight; Quantitative trait loci; Rice husk

Grain shape and weight are the most important components of rice yield and are controlled by quantitative trait loci (QTLs). In this study, a double-haploid population, derived from the cross of japonica CJ06 and indica TN1, was used to analyze QTLs for grain shape and weight under two conditions: normal growth with unbroken husk and removing partial husk after flowering ... more

Breeding; Cultivated oat; SSR; Wild oat

Preservation and use of wild oat species germplasm are essential for further improvement of cultivated oats. We analyzed the transferability and utility of cultivated (white) oat Avena sativa (AACCDD genome) microsatellite markers for genetic studies of black oat A. strigosa (AsAs genome) genotypes. The DNA of each black oat genotype was extracted from young leaves and ... more

In order to support further genetic, diversity, and phy­logeny studies of Capsicum species, the transferability of a Capsicum annuum L. simple sequence repeat (SSR) microsatellite set was ana­lyzed for C. frutescens L. (“malagueta” and “tabasco” peppers) and C. chinense Jacq. (smell peppers, among other types). A total of 185 SSR primers were evaluated ... more

Correlation analysis; Growth-related traits; Multiple regression equation; Path analysis; Scylla paramamosain

In this study, we analyzed the correlation of 20 growth-related traits and their effects on body weight of Scylla paramamosain. The correlation coefficients in all trait pairs were significantly high, ranging from 0.551 to 0.999. Among 19 X-Y pairs, the correlation coefficient between traits X1 and Y was the highest, whereas that ... more
